The Battle of Shiloh, also known as the Battle of Pittsburg Landing, was a major battle in the Western Theater of the Civil War and was one of the bloodiest battles in U.S. history up to that time. It was fought from April 6 to the 7th in southwestern Tennessee.

The Confederates, under General Albert S. Johnston, were forced to retreat from the battle, ending hopes of blocking the Union army and Major General Ulysses S. Grant, from advancing into northern Mississippi. Casualties included 2,400 killed and over 3,000 wounded.
